Bariatric & Metabolic Surgery

It is a group of operations, usually done laparoscopically, that change the stomach and sometimes the intestine to help patients lose weight and improve conditions such as type 2 diabetes, high blood pressure and sleep apnea.

Eligibility is decided after clinical assessment. Guidelines generally consider adults with a BMI of 35 or more, or lower BMI thresholds (about 27.5 to 32.5 for Asian patients) when obesity-related conditions such as diabetes are present and non-surgical methods have not worked.

We offer laparoscopic sleeve gastrectomy, laparoscopic Roux-en-Y gastric bypass, metabolic surgery for diabetes and revision bariatric surgery.

About 75 to 80 percent of the stomach is removed, leaving a narrow tube-shaped stomach. This limits food intake and reduces hunger hormones.

A small stomach pouch is created and connected directly to the small intestine, bypassing part of the stomach and upper intestine. It restricts food intake and alters gut hormones, and is often chosen for patients with diabetes or severe reflux.

Many patients achieve remission or major improvement in blood sugar after surgery, often reducing or stopping medication. Results vary with the duration of diabetes, the procedure and lifestyle follow-up, and long-term monitoring is still needed.

Most patients lose a substantial portion of their excess weight, typically within 12 to 18 months. The amount depends on the procedure, diet, activity and adherence to follow-up.

Modern laparoscopic bariatric surgery has a safety record comparable to other common abdominal operations when performed by an experienced team after thorough pre-operative evaluation. All surgery carries risks, which are discussed before the procedure.

Most patients stay about 2 to 3 days after laparoscopic surgery, depending on the procedure and recovery.

Many patients resume desk work in one to two weeks. Strenuous activity and heavy lifting are usually avoided for about four to six weeks, as advised by your surgeon.

Evaluation usually includes blood tests, HbA1c, thyroid and liver assessment, ECG, chest imaging, abdominal ultrasound, upper GI endoscopy, anaesthesia review and dietitian counselling. A sleep study may be advised if sleep apnea is suspected.

Diet progresses from liquids to pureed food, soft food and then normal solid food over several weeks. A dietitian guides portions, high-protein intake and hydration.

Yes. Multivitamins, calcium, vitamin D, iron and vitamin B12 are commonly prescribed, and periodic blood tests check for deficiencies.

Some weight regain can occur over time, especially without lifestyle changes and follow-up. Revision bariatric surgery may be considered in selected patients.

Revision surgery corrects or converts a previous weight-loss operation when there is significant weight regain, inadequate weight loss or a complication, after detailed assessment.

Weight loss after surgery often reduces the severity of obesity-related sleep apnea, and some patients can reduce or stop CPAP use under medical supervision.

Fertility often improves with weight loss. Pregnancy is generally advised after 12 to 18 months, once weight has stabilised, with nutritional monitoring.

Coverage depends on the insurer and policy terms, which often require documented BMI and obesity-related conditions. Our team can help with documentation and pre-authorisation.
